Some critics showed concern over 12-year-old Foster's presence during the climactic shoot-out.<ref>{{cite web|url=https://www.vanityfair.com/hollywood/2016/04/jodie-foster-taxi-driver-robert-de-niro-martin-scorsese/amp|title=Jodie Foster recalls working with Robert De Niro and Martin Scorsese in Taxi Driver as a Kid|work=[[Vanity Fair (magazine)|Vanity Fair]]|author-first1=Julie|author-last1=Miller|date=April 7, 2016 |access-date=November 17, 2020|archive-date=January 16, 2021|archive-url=https://web.archive.org/web/20210116214823/https://www.vanityfair.com/hollywood/2016/04/jodie-foster-taxi-driver-robert-de-niro-martin-scorsese/amp|url-status=live}}</ref> Foster said that she was present during the setup and staging of the special effects used during the scene; the entire process was explained and demonstrated for her, step by step. Moreover, Foster said that she was fascinated and entertained by the behind-the-scenes preparation that went into the scene.

In addition, before being given the part, Foster was subjected to [[psychological testing]], attending sessions with a [[University of California, Los Angeles|UCLA]] psychiatrist, to ensure that she would not be emotionally scarred by her role, in accordance with [[California Labor and Workforce Development Agency|California Labor Board]] requirements monitoring children's welfare on film sets.<ref>{{Cite web |url=https://www.independent.co.uk/arts-entertainment/films/news/jodie-foster-details-how-uncomfortable-it-was-playing-a-prostitute-aged-12-in-taxi-driver-a7040016.html |title=Jodie Foster details how 'uncomfortable' it was playing a prostitute aged 12 in Taxi Driver |author-first1=Christopher|author-last1=Hooton|website=[[The Independent]] |date=May 20, 2016 |archive-url=https://web.archive.org/web/20190226052352/https://www.independent.co.uk/arts-entertainment/films/news/jodie-foster-details-how-uncomfortable-it-was-playing-a-prostitute-aged-12-in-taxi-driver-a7040016.html|archive-date=February 26, 2019|url-status=live}}</ref><ref name="keyser">{{Cite book |title=Martin Scorsese |last=Keyser |first=Les |year= 1992|isbn=0-8057-9315-1 |url=https://archive.org/details/martinscorsese0000keys |page=94|publisher=Twayne }}</ref>

Additional concerns surrounding Foster's age focused on the role that she played as Iris, a prostitute. Years later, she confessed how uncomfortable the treatment of her character was on set. Scorsese did not know how to approach different scenes with the actress. The director relied on Robert De Niro to deliver his directions to the young actress. Foster often expressed how De Niro, in that moment, became a mentor to her, stating that her acting career was highly influenced by the actor's advice during the filming of ''Taxi Driver''.<ref>{{Cite interview |url=https://www.wmagazine.com/story/forty-years-after-taxi-driver-and-her-first-oscar-nomination-jodie-foster-recalls-the-making-of-a-classic |title=Forty Years After "Taxi Driver," Jodie Foster Recalls the Making of a Classic |date=September 22, 2016 |archive-url=https://web.archive.org/web/20190216035125/https://www.wmagazine.com/story/forty-years-after-taxi-driver-and-her-first-oscar-nomination-jodie-foster-recalls-the-making-of-a-classic|archive-date=February 16, 2019|url-status=live|interviewer-first1=Lynn|interviewer-last1=Hirschberg|author-last1=Foster|author-first1=Jodie|website=W}}</ref>
